3. A diffraction grating has 2500 lines/cm. a) What is the value of d for the diffraction grating? (2 pts K) b) How would turning the diffraction grating by 90° change the interference pattern you observe? (2 pts C) c) If blue light (A=480 nm) is shone through the diffraction grating and produces a pattern of dots as shown, how far away was the diffraction grating from the screen? (3 pts A) 22 cm 3.
